Hi, at the end this worked for me:
:; cat<<EOF|lxd init --preseed cluster: enabled: true server_name: ${HOSTNAME%%.*} server_address: ${HOSTNAME%%.*}:8443 cluster_address: cluster:8443 cluster_certificate: "$(sed ':a;N;$!ba;s/\n/\n\n/g' /tmp/cluster.crt) " cluster_password: “password" member_config: - entity: storage-pool name: your-storage-pool-name key: source value: yourzfspool/yourzfsfs EOF the trick is that you have to first migrate or delete all the existing containers on the joining node and destroy the storage pool if it has the same name as the cluster pool. New node can only join the cluster completely empty, I don’t know why I was somehow expecting that the existing containers will be merged with the ones in the cluster. It is a nice feature request though ;) > On 4.
